LUDWIG F. C. HAAS AND ERNEST J EHEBER, OF LANCASTER, PENNSYLVANIA.

MECHANICALLY-OPERATED DRESS-FORM.

To all whom, it may concern Be it known that we, LUDWIG F. C. HAAs and ERNEST J EHEBER, citizens of the United States, residing at Lancaster, in the county of Lancaster and State of Pennsylvania, have invented certain new and useful Improvements in Mechanically-Operated Dress- Forms, of which the following is a specification.

This invention relates to an improved dress form and more particularly to the mechanically operated type wherein means is provided for imparting motion thereto to better display the dress or apparel arranged thereupon.

The primary object of the invention contemplates the provision of means adapted to be employed in connection with a suitable dress form or model whereby a correct imitation of the movement of the human being is imparted to the apparel or dress upon the form, thereby better displaying the fit and appearance of the dress as it would appear upon the wearer.

A further object of the invention resides in the provision of a specially devised form particularly adapted for show cases and store windows wherein the form, with the dress or apparel arranged thereupon is moved after the fashion of the human being, thus permitting the observer to determine the advanta es and faults of the apparel displayed, the form or model being operated to walk and move mechanically throughout the length of a suitable track way provided therefor.

The above and additional objects are accomplished by such means as are illustrated in their preferred embodiment in the accompanying drawings, described in the following specification and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

In describing the invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or corresponding parts throughout the several views and in which;

Figure 1 is a side elevation of the mechanical dress form constructed in accordance with our invention, one of the fioor sections and a portion of the device being shown in section, and the dress being shown in dotted lines; Fig. 2 is a section on the line 2-2 of Fig. 1; Fig. 3 is a section on the line 33 of Specification of Letters Patent.

Application filed June 25, 1913. Serial No. 775,830.

Fig.1; and, Fig. 4 is a diagrammatic view of the electric circuit.

Referring now to the drawings, wherein is illustrated the preferred form of our inven-' tion, the numeral 1 designates the stationary floor of a show case or store window to which are secured the rails 2 from which the electric currentnecessary to the operation of our device is derived, the said rails being preferably L-shaped in cross section and screwed or otherwise secured as at 3 to a block or strip of suitable insulating m aterial 4::arrangedbetween the base of the said rails and the floor 1. A second or removable floor SGCtlOIl 5 is arranged in spaced relation over and above the stationary'floor l,-

the former having an opening 6 formed therein directly over the rails 2 above mentioned, the said opening permitting the.

frame of the mechanical dress form comprising our invention, to extend therethrough.

A guide rail 7 is secured in any suitable manner to the floor section 5 within the opening 6 formed therein, the said rail 7 supporting the frame work of the dress form in a manner to be hereinafter fully deto the mechanical structure comprising our invention, the motor deriving its electric current from a pair of contact brushes 10 mounted on an extension 12 of the carriage fitting between the rails, the brushes being directly engageable with the adjacent faces of the respective rails as is clearly shown by the diagrammatic view in Fig. 4 of the drawings. A- switch 13 of any suitable type may be employed for the purpose ofmaking and breaking the circuit as occasion demands.

A driven shaft 14 projects from the motor 10 and has keyed or otherwise fixedly secured thereto, a gear wheel 15, the said wheel meshing into a second gear wheel 16 mounted upon a shaft 17 extending longitudinally of the carriage frame 8. A worm gear 18 is arranged or mounted centrally upon the shaft 17 and is adapted to mesh into a large gear wheel 19 which is in turn mounted upon a shaft 20 extending transversely of the shaft 17 and supported through the medium of a cross beam 21' forming a part of the carriage frame. The said gear wheel is provided with a bevel face gear 22 which is adapted to mesh into a bevel pinion 23 mounted upon the lower extremity of a vertically extending shaft 24 ournaled within an upright frame portion 25 formed integrally with the carriage 8, the said frame portion terminating at its upper extremity in a head or enlargement .26, the purpose of which will subsequently appear. A smaller, gear wheel 27 is mounted upon the trans-' versely extending shaft 20 andis adapted to mesh into teeth 28 formed upon the lower edge of the guide rail 7, this arrangement causing the carriage to move along the said rail according to the rotation of the gear 27.

Rollers 29 are mounted upon the carriage 8, in spaced relation to the rollers 9 above mentioned, the said rollers 29 engaging the lower edge of the guide rail 7, and with the rollers 9 supporting the upright frame portion 25 in the desired manner.

Double crank arms 30 are formed integrally with the vertically extending shaft 24, the said arms working within the head 26 of the upright frame, each having secured thereto a collar 31 to which is pivotally secured as at 32 a link 33, the latter terminating in a knee cap 34 which is adapted to engage the dress or apparel arranged over the form. The means employed for supporting the link 33 in the desired manner comprises an arm 35 carried by theupright frame portion 25 which terminates at its, upper extremity in the bifurcated end 36 having a pin 37 extending therethrough thesaid pin working within an elongated aperture or slot 38 formed within a second link 39 pivotally secured as at 40 to the extremity of the link 33. By this arrangement, it will be seen that the said link 33 is supported in the desired manner and is permitted to work back and forth according to the movement of the crank arm 30 thereby moving the dress or apparel by reason of its contact with the knee cap 34 in the desired manner, the slot 38 permitting the lever 39 to move vertically during the reciprocation f the lever 33. Likewise pivotally secured to the link 33 as at 40 and depending therefrom is a lever 41, the opposite end of which is pivotally secured as at 42 to a shoe form 43, the toe of which is weighted so as to be normally held in engagement with the upper face of the floor section 5. Another link 44 is pivotally secured as at 45 to the link 33, the last mentioned link being pivotally secured as at 46 to a pair of smaller links 47 and 48, the former being eccentrically and pivotally secured as at 49 to a wheel 50 mounted for rotation upon the carriage frame 8, while the other lever 48 is pivotally secured as at 51 to the shoe form 43. This arrangement of the levers 41, 44, 47 and 48 will actuate the shoe form 43 in the desired manner and will cause the same to move back and forth from beneath the dress or apparel arranged upon the form thereby producing a correct imitation of the movement of the foot when walking.

Having described the detail construction of the mechanical dress form, it now remains tov set forth in detail the operation thereof.

The motor 10 deriving its power from the rails 2 through the medium of the contact plates or brushes 12, drives the gear 15 which in turn drives the shaft 17, the latter imparting motion to the large gear wheel 19. The rotation of the gear 19 transmits motion to the smaller gear 27, which, by reason ofits engagement with the teeth 28 of the, guide rail, moves the entire carriage along the said rail according to the rotation of the said gear 27, the rollers 9 supporting the carriage and the upright frame portion 25 in the desired manner. The rotation of the bevel gear 22 imparts motion to the vertically extending shaft 24 for turning the crank arms 30 of the device, the movement of the said arms actuating the knee caps 34 and the foot forms 33 in the desired manner. The provision of the links 44, 47, and 48 causes the foot form 43 to move back and forth between the edge of the skirt or dress, this being governed by the rotation of the wheels 50 having the lever 47 eccentrically pivoted thereto. Lateral movement of the entire frame with respect to its support is guide rail 7 and the contact plates 2 he 'made in sections to render the installation of the device less troublesome, the said track way being curved before being placed within the store window or show case in connection with which our device is used.

It will be seen from the above, taken in connection with the accompanying drawings that the former device is moved forwardly by reason of the engagement between the pinion 27 and the teeth 28 of the guide ways 7; that the disposition of the crank arms 30 with respect to one another will alternately move the knee caps 34 and the foot forms 43 as occasion demands; and that further linkage may be provided and operated from the same source for mechanically moving the arms, the head and the eyes of the form or model if so desired, this being left to the discretion of the manufacturer in the practical application of the invention.

In reduction to practice, we have found that the form of our invention, illustrated in the drawings and referred to in theabove description, as the preferred embodiment, is the most efiicient and practical; yet realizing that the conditions concurrent with the adoption of our device will necessarily vary, we desire to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of our invention, as defined in the appended claims.
